- In the Device Manger list, navigate to your Universal Serial Bus Controllers, then select the 'USB Root Hub' device, right click it and select Properties.
- In the 'USB Root Hub' Properties select 'Power Management' from the options at the top, now turn off the setting 'Allow the computer to turn off this device to save power'.
